Our shipping folks insist on packaging board level assemblies in static shielding bags and HEAT SEALING them. As I recall several years ago I heard that heat sealing plastic bags for PCBs at the board level was bad. Seems as if some vapors were deposited on the fab decreasing the solderability. Does anyone know of a reason to require that these bags be taped shut and not heat sealed???
